This innovative product is built with the needs of active children in mind, providing them with the freedom to explore, play and stay focused all season long. The ColdGear Mock Long Sleeve features a dual-layer fabric, combining an ultra-warm, brushed interior that locks in warmth and a smooth, fast-drying exterior that repels moisture. These two layers work together to ensure your child remains dry and comfortable, even in the coldest conditions. But the features don't stop there. The back and underarm areas of the garment are equipped with stretch-mesh panels, providing strategic ventilation to keep your child cool during high-energy activities. The 4-way stretch material ensures better movement in all directions, so whether they're running, jumping, or playing, they'll experience the ultimate in mobility and comfort. This baselayer also boasts a moisture-wicking material that dries exceptionally fast, keeping sweat at bay and ensuring your child stays dry and comfortable. The cleverly designed ergonomic seams are kept off of high abrasion areas to increase the durability of the garment and provide even more comfort. The ColdGear Mock Long Sleeve also features a mock neck construction for added coverage and warmth, as well as a dropped, shaped hem for a sleek, modern look. The fit is streamlined, ensuring it’s not too tight or too loose, providing the perfect balance for active wear. Crafted from a blend of 87% Polyester and 13% Elastane, this piece is both soft and stretchy, ensuring it keeps up with all your child's adventures. The Under Armour Boys ColdGear Mock Long Sleeve Apparel is available in a variety of colors to suit every child's style and personality. With its combination of performance, comfort, and style, the Under Armour Boys ColdGear Mock Long Sleeve Apparel is the ideal piece for the active child in your life.
